Transverse charge and spin transport within the Kubo-Bastin formalism — •Kristina Chadova, Diemo Ködderitzsch, and Hubert Ebert — Universität München, Department Chemie, Butenandtstr. 5-13, D-81377 München

In recent years several first-principles approaches have been established to treat transverse electron transport phenonmena as e.g. the anomalous Hall effect and spin Hall effect. Most of them treat particular contributions to the full conductivity tensor. We present a first-principle approach based on the Kubo-Bastin equation implemented withtin the fully relativistic KKR (Korringa-Kohn-Rostoker) formalism that is able to treat intrinsic and extrinsic contributions on equal footing. Both contributions from states below ("Fermi sea") and at the Fermi level ("Fermi surface") are treated and can be analysed with respect to constituting the full transverse conductivities. The approach is applicable to pure systems as well as metallic and semiconductor alloy systems. Several applications are presented that demonstrate the reliability and the power of the proposed scheme.
